Sleepeezee Fusion Pro Mattress
The Sleepeezee Fusion Pro is a hybrid mattress that pairs 800 pocket springs with a copper-infused memory foam top layer, which means you get responsive support underneath with a pressure-relieving surface that's designed to shed heat rather than trap it.

At 25cm deep with a Medium-Firm feel, the Sleepeezee Fusion Pro suits most sleepers, although anyone who prefers a soft, sink-in surface may find it a little unyielding. It's available in UK Single through to UK Super King. It also holds a Which? Best Buy award, which is reassuring at a mid-range starting price.

Why should you choose this mattress?
If you're a hot sleeper who still wants memory foam, this is where the Fusion Pro makes its case. The copper-infused foam is designed to move body heat away faster than standard memory foam, and Sleepeezee says the copper adds antimicrobial properties too. Beneath that, a white fibre filling cushions spring movement and helps reduce allergens, and the 800 pocket springs adjust independently to your shape, which means less partner disturbance and support that follows your body rather than fighting it. Yes, 800 is a modest spring count compared with some premium hybrids, but the Which? Best Buy award and a mid-range starting price make it a sensible middle ground rather than a compromise.
Key features & layer details
Copper Infused Memory Foam
The top layer uses memory foam infused with copper, which helps reduce heat build-up and moves body heat away more quickly, so you should feel noticeably cooler than on standard memory foam. Sleepeezee also credits the copper with antimicrobial properties.
White Fibre Filling
A white fibre filling sits between the foam and the springs, cushioning spring movement so you feel a smoother surface rather than individual coils. It also helps reduce allergens, a small but welcome touch for sensitive sleepers.
800 Pocket Springs
The base is 800 traditional pocket springs that adjust independently, which means support that responds to your body shape rather than the whole bed moving as one. That independence also helps limit disturbance when a partner shifts position.

Best suited for?
Warm sleepers
The copper-infused memory foam top layer moves body heat away faster than standard memory foam, so you should feel cooler through the night.
Couples
Each of the 800 pocket springs adjusts independently, which limits the disturbance you feel when a partner shifts position during the night.
Allergy sufferers
A white fibre filling between the foam and the springs helps reduce allergens, which makes this a sensible pick for sensitive sleepers.
Back sleepers
The Medium-Firm feel and independently adjusting pocket springs give support that follows your body shape, keeping a steady, supportive surface beneath you.
Combination sleepers
A Medium-Firm feel suits most sleepers, and the fibre layer smooths out the springs so changing position doesn't feel like moving across individual coils.
This isn't the mattress for you if you love a soft, enveloping feel: Medium-Firm has a supportive character, and lightweight side sleepers may find it slightly too firm at the shoulders and hips. Anyone wanting an all-foam feel with no spring response should also look elsewhere.
Save on an earlier or ex-display model

FAQ's
Is the Sleepeezee Fusion Pro firm or soft?
Sleepeezee rates it as Medium-Firm. In practice that means a supportive feel with some surface cushioning from the copper-infused memory foam, rather than a soft, sink-in sensation. It suits back and combination sleepers well, although lighter side sleepers may find it a touch firm.
How deep is the Sleepeezee Fusion Pro mattress?
It's 25cm deep, which fits standard fitted sheets comfortably. That depth covers the copper-infused memory foam, a white fibre filling and the 800 pocket spring unit.
Does the Sleepeezee Fusion Pro sleep hot?
It's designed not to. The top layer is copper-infused memory foam, and copper helps reduce heat build-up and moves body heat away more quickly than standard memory foam. If you've found memory foam mattresses too warm before, this is one of the cooler-running options.
What guarantee does the Sleepeezee Fusion Pro come with?
Retailer listings for this mattress show a 10 Year Guarantee. Terms can vary by seller, so it's sensible to confirm the guarantee with whichever retailer you buy from.
How much does the Sleepeezee Fusion Pro cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It's available in UK Single, UK Double, UK King and UK Super King.
